It is not really an Android SDK question. You did not post the Client code that receives the file. Your stacktrace indicates that the connection got closed (maybe by the client), while you are still trying to write to it. There are HTTP Headers for connection management. Do you specify these?
You handler in the GET path does not serve 'Content-Length' header to let the client know, how much to expect. You could also use Transfer-Encoding: chunked' instead, but then you need to serve your file in a specific way. You could explicitly specify the connector to the server with directly defined ThreadPool (number of worker threads serving the connections), rather than relying on unknown defaults. http://wiki.eclipse.org/Jetty/Tutorial/Embedding_Jetty#Configuring_Connectors Daniel On 18 April 2012 14:04, Kiran <[email protected]> wrote: > I should add that the errors that I've posted are appearing on the server > side, not the client side.
